High-precision GNSS from u-blox

Posted 27 September 2022

u-blox has released a new firmware update which extends the range of positioning augmentation services supported by its ZED-F9R high precision GNSS dead reckoning modules. Thanks to a firmware update, the u-blox ZED-F9R-03B adds support for SPARTN 2.0 and QZSS CLAS correction services, extending the geographical market reach of the ZED-F9R and increasing the scalability of applications using the module.

The module has an integrated inertial measurement unit (IMU) for RTK positioning and employs sophisticated algorithms to fuse the IMU data with GNSS measurements, wheel ticks, correction service data, and a vehicle dynamics model to provide centimeter-level positioning accuracy even in situations where GNSS alone would fail.

The RTK (Real-Time Kinematic) capable ZED-F9R module was designed for use in autonomous automotive and industrial applications that require simple and efficient implementation and where rapid access to highly accurate positioning data is key, even in challenging signal environments as found in dense cities. Typical applications include slow moving use cases such as robotic lawnmowers and shared e-scooters.
